Hexagon has just released the latest NCSIMUL CAM simulation package from its Production Software portfolio. It includes a number of enhancements to high-end machining verification and the module, which automatically converts CAM and NC programs to different machines. The three main topics that developers focused on in this latest release are: Optipower; interface enhancements and 4CAM.

NCSIMUL 2020.1 introduces an additional parameter to NCSIMUL Machine. Optipower complements the Optitool module by adding the necessary power and torque to remove material.

Technical Director Philippe Legoupi says it is used as a limitative parameter, which optimizes the program and limits power, so that risks of breakage are avoided. A graph shows the evolution of the power on the tool, so it can be limited to avoid possible flexions, overheating and premature deterioration.

The interface has been enhanced with two main developments, which Legoupi says are valuable for optimizing programs. “The aim is to save time through automated tools, and give a better and clearer view of work through enhanced navigation,” he says.

Firstly, a “graph window” has been added, enabling users to zoom in to focus on a specific tool rather than being restricted to a simple overview. “The choices are saved in the project window—so even if you need to watch another part of the program, the focus created on the chosen tool will be saved in the project. Also, the color of the focused graph matches the color of the toolpaths on the 3D view, which is helpful in giving a clear vision of the machining process at a glance.”

Secondly, there is now the option of choosing a specific sequence in the arborescence. According to Legoupi, by applying the F7 key, users can now reach the chosen place in the program, in the window they need. The milling sequence window is linked to the project tree, so it’s possible to navigate freely from one to the other.

The 4CAM part of the digital twin solution benefits from enhancements including:

supports native polar toolpaths for mill-turn machines;

a new link for twin-head machines, and a change of rotation for safer positioning; and

general improvements such as axis system duplication and more realistic rendering without slowing the process.
